Win / Loss Sparklines
Win / loss sparklines show you whether your data is positive (a win) or negative (a loss).
The sparkline displays these differences by placing positive data above the sparkline's X axis (zero line) and negative data below the X axis. The axis line is not shown, but it is situated in the middle of the cell.
If you have a zero value in your data it is treated like a blank cell and no bar is displayed for that cell. A gap is left in the sparkline.
In the example above, the win / loss sparkline reflects the positive growth for the stock in the years 2007, 2008, and 2010 with green bars above the X axis. The loss in stock value in 2009 is shown by the red bar located below the X axis.
